Genes affected

FOXD4L1 (HGNC:18521): (forkhead box D4 like 1) This gene is a member of the forkhead/winged-helix (FOX) family of transcription factors with highly conserved FOX DNA-binding domains. Members of the FOX family of transcription factors are regulators of embryogenesis and may play a role in human cancer. This gene lies in a region of chromosome 2 that surrounds the site where two ancestral chromosomes fused to form human chromosome 2. This region is duplicated elsewhere in the human genome, primarily in subtelomeric and pericentromeric locations, thus mutiple copies of this gene have been found. [provided by RefSeq, Jul 2008]

Dec 16, 2023

The c.605G>A (p.R202H) alteration is located in exon 1 (coding exon 1) of the FOXD4L1 gene. This alteration results from a G to A substitution at nucleotide position 605, causing the arginine (R) at amino acid position 202 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
